Morro Bay Harbor, CA, was selected for inclusion in the Monitoring Completed Navigation Project Program in 1997 and monitoring was initiated in 1998. The objective was to determine if nonstructural modifications at the harbor entrance were performing as predicted by design tools. Monitoring included the collection of wave and current data, bathymetric data, and ground and photogrammetric surveys of the south breakwater. This report presents wave and current data obtained at the site during the monitoring effort. A subsequent report will provide further analysis as well as results of the comprehensive monitoring effort.
